I Specification of Letters Patent.

Patented Jan. 14, 1919.

Application filed August 29, 1918. Serial No. 251,912.

To all whom it may concern:

Be it known that I, STEPHEN A. Near, a

7 subject of the Emperor of Germany, and residing at Detroit, in thecounty of Wayne and State of Michigan, have invented a new and ImprovedMachine for Making Soft- Metal Wire, of which the following is aspecification.

This invention relates to the manufacture of thin rods or wires of lead,tin, solder or other readily fusible metals or alloys, and its object isto provide a machine for this purpose which .will require a minimum ofattention, which can be constructed at low cost, and which. will producewires or rods of uniform size.

This invention consists in a circular table turning on a. vertical axisand having a smooth upper surface, of a receptacle for the melted metalositioned over this surface and substantia ly contacting therewith, thereceptacle being provided .with small apertures to discharge the meltedmetal onto said table, and means to supply melted metal to saidreceptacle. It also consists in providing means for maintaining theliquid metal in said receptacle at a constant level. It further consistsin means for keeping the metal in said receptacle and adjacent theretoat high temperature.

In the accompanying drawings, F lgure 1 I is an elevation of thisimproved wire-forming machine. Fig. 2 is a plan of the driving mechanismlooking down from the line 2-2 of Fig. 1. Fig. 3 is a plan of themachine. Fig. 4 is a section of the trailer and val e on the line 4-4 ofFig. 3 on a larger scale.

Similar reference characters refer to like parts throughout the severalviews.

The table 1 which constitutes a portion of this invention is mounted ona perpendicular shaft and turned by means of any desired mechanism. Inthe drawings, a frame consisting of legs 2 and cross bars 3 and 4supports a base for the motor 5 and the bear ings for the shafts 6, 7and '8. A worm 9 on the motor shaft 6 meshes with the wormwheel 10 onthe shaft 7. A chain 12 connects the sprocket wheel Ben the shaft 7 tothe sprocket wheel 14 on the table shaft 8.

The upper surface of the table, or at least the outer portion of thissurface is level and smooth. Above it is mounted the trailer 16, a recetacle having an inclined bottom 17 and a front side 18, the edge betweenthe two being preferably rounded and formed with any desired number ofdischarge passages 19. The sizes of these passages will depend upon thediameters of the wires to be pro-- duced.

' A bracket 21 extends up from the frame I and supportsa melting pot 22which may be heated by a flame from the burner 23 supplied by a pipe 24.A jet of gas impinges on the metal in the trailer, being directedthereto by the nozzle 25 supplied by the pipe 26. Valves 27 and 28 maycontrol these flames. An arm 29 extends from the bracket 21 to supportthe trailer. A dross pan 30 may be supported adjacent the melting pot 22by means of a bracket 32.

The melted metal flows from the pot 22 to the controller 33 through apipe 34. While any desired means may be employed to regulate the flowfrom this controller to the trailer, I prefer to use a valve 35connected which will cause the valve 35 to stop the flow of metal fromthe opening 41 when the desired height of metal in the trailer isreached. In other words, this valve and float will automatically keepconstant the level of the metal in the trailer and thereby the pressureof the liquid metal at the openings or passages 19 will be kept constantand the flow of metal through these passages will be kept uniform. Theflame from the nozzle 25 will also keep the discharge end of thecontroller very hot and thereby prevent hardening of the metal therein.

The ta le may be kept clean by a pad or wiper 44 held in position by arod 45 secured to the frame and extending up around and over the table.A rod 46 supported by brackets 47 carriessmall hooks 48 over which thewires 49, 50, 51, 52 and 53 are passed so that their weight will slidethem off the table to the places where they are coiled, the outside wirebeing removed first. A rod 54 extends up from the frames over the tableand at the beginning of the manufacture of these wires, the severalwires are lifted up above this rod which thereafter will serve to loosenthe wires from the table so that they can be easily removed by the hooks48. I have found that wires of solder of No. 19 gage may be formed on atable about four feet in diameter running from thirteen to sixteenrevolutions per minute. While five wires are shown,- this machine iscapable of simultaneously producing many more, but each wire should havea separate hook 48 to conduct it to the place whereit may be coiled.

The details and proportions of this machine may all'be changed withoutdeparting from the spirit of my invention as set forth in theaccompanying claims.

1. In a wire forming machine, the combination of a smooth circular tableand means to turn it on a vertical axis, and a trailer mounted above thetable and formed to discharge a plurality of fine streams of meltedmetal onto the horizontal top of the table.

2. In a wire forming machine, the combination of a circular table havinga smooth horizontal top, means to turn the table on a vertical axis,means to deposit a plurality of fine streams of melted metal'onto thetop of the table to form wires, a rod extending across the table at itsedge over which the metal wires will pass and means to slide the wiresofi' the edge of the table.

3. In a wire forming machine, the combination of a smooth circular tableand means to turn it on a vertical axis, and a trailer mounted above thetable and formed to discharge fine streams of melted metal onto thesmooth horizontal top of the table, and

means to control the rate of flow of the I liquid metal.

4. In a wire forming machine, the combination of a constantly movingreceiver having a smooth horizontal surface, a receptacle for meltedmetal adjacent the receiver and having a discharge opening to direct afine stream of melted metal onto this smooth moving horizontal surface,and means to control the rate of flow of the liquid metal from saiddischarge opening and means'to ed above the table and formed todischarge a plurality of fine streams of melted metal onto the top ofthe table, and means for each resulting wire to cause it to slideradially from the table, the outer wire on the table being the first tobe removed therefrom.
